PHP Question

Joomla 2.5 get component configuration in config.xml ALWAYS return null

Please help me with this

I am creating a component. There is a config.xml in my component
I write my custom JFormFieldUserCheck
in userCheck.php I want to load parameter or field from config.xml

I used

$param = JComponentHelper::getParams('com_my-component');

Resul is

object(stdClass)#214 (0) { }

But when I change com_my-component to com_content (Joomla default component).
then var_dump, result is fine.

Thanks in advance

I have added an excerpt from the blog entry:

Plugin parameters from inside a plugin

$param = $this->params->get('paramName', 'defaultValue'); 

Plugin parameters from outside a plugin

$plugin = &JPluginHelper::getPlugin('exampleType', 'example');
$pluginParams = new JParameter($plugin->params);
$param = $pluginParams->get('paramName', 'defaultValue'); 

Module parameters from inside a module

$param = $params->get('paramName', 'defaultValue'); 

Module parameters from outside a module

$module = &JModuleHelper::getModule('example');
$moduleParams = new JParameter($module->params);
$param = $moduleParams->get('paramName', 'defaultValue'); 

Component parameters from inside a component

$componentParams = &JComponentHelper::getParams('com_example');
$param = $componentParams->get('paramName', 'defaultValue'); 

Component parameters from outside a component

$componentParams = &JComponentHelper::getParams('com_example');
$param = $componentParams->get('paramName', 'defaultValue'); 

Template parameters from inside a template

$param = $this->params->get('paramName'); 

Template parameters from outside a template

$mainframe = &JFactory::getApplication();
$params = $mainframe->getParams(JFile::read(JURI::root() .'/templates/template_name/params.ini'));
$param = $params->get('paramName', 'defaultValue'); 

Template parameters from an included file outside the Joomla framework

// Get params.ini relative to the current file location (use your own relative path here)
$paramsFile = dirname(__FILE__) . '/../../params.ini';

// Only continue if the file exists
if(file_exists($paramsFile)) {
// Get contents from params.ini file
$iniString = file_get_contents($paramsFile);

// Escape double quotes in values and then double-quote all values (because Joomla doesn't do that for us..)
$iniQuoted = preg_replace('/=(.*)\\n/', "=\"$1\"\n", addcslashes($iniString, '"'));

// Parse the ini string to an associative array
$iniParsed = parse_ini_string($iniQuoted);
} else {
$iniParsed = '';

// Set params to obtained values or empty array
$params = (!empty($iniParsed)) ? $iniParsed : array();

// Get param value from array
$param = $params['paramName'];
